fix(ci): gate new release packages on npm bootstrap (#5146)

## Thinking Path

> - Paperclip is a control plane for autonomous agent companies, so its
release automation is part of the core operator trust boundary.
> - The affected subsystem is npm/GitHub Actions release publishing for
the public monorepo packages.
> - The concrete failure was that a newly added package reached
`master`, the canary workflow attempted its first publish, and npm
trusted publishing was not yet bootstrapped for that package.
> - That means the problem is not just one broken run; it is a missing
pre-merge guard that lets release-ineligible packages land and only fail
once `publish_canary` runs.
> - This pull request makes release enrollment explicit, validates that
enrollment in CI, and adds a PR-time bootstrap check against npm for
changed release-enabled package manifests.
> - The result is that we keep trusted publishing, avoid teaching CI to
`npm adduser`, and move this class of failure from post-merge canary
time to pre-merge review time.

## What Changed

- Added `scripts/release-package-manifest.json` so release-managed
public packages are explicitly enrolled instead of being inferred from
every non-private workspace package.
- Hardened `scripts/release-package-map.mjs` to validate the manifest
before release workflows rewrite versions or assemble publish payloads.
- Added `scripts/check-release-package-bootstrap.mjs` and wired it into
`.github/workflows/pr.yml` so PRs that change a release-enabled package
manifest fail if that package does not already exist on npm.
- Added release-package manifest coverage tests to
`scripts/release-package-map.test.mjs` and included them in `pnpm run
test:release-registry`.
- Wired manifest validation into `.github/workflows/release.yml` and
documented the first-publish bootstrap policy in `doc/PUBLISHING.md` and
`doc/RELEASE-AUTOMATION-SETUP.md`.

## Verification

- `pnpm run test:release-registry`
- `./scripts/release.sh canary --skip-verify --dry-run`
- Confirmed the committed diff contains no obvious PII/secrets via
targeted pattern scan before pushing.

## Risks

- Low risk overall: this is CI/release-policy code, not product runtime
logic.
- The new PR bootstrap check depends on npm metadata availability, so a
transient npm outage could block a PR that changes a release-enabled
package manifest.
- The manifest introduces a new source of truth that must stay aligned
with public package additions, but that is intentional and now enforced.

## Model Used

- OpenAI Codex via the `codex_local` Paperclip adapter; GPT-5-based
coding agent with tool use, terminal execution, git, and GitHub CLI.
Exact served model ID/context window are not exposed by the local
runtime.
